Clutch release bearing in contact with a disk spring

A clutch release bearing in contact with a disk spring, the clutch release bearing comprises at least one curved contact surface, each of the at least one curved contact surfaces is set at a radial distance to an axis of rotation of the clutch release bearing for contacting a respective at least one end of a respective spring tongue of the disk spring, each of the at least one curved contact surfaces is defined by an arbitrary number of straight surface lines adjacent to each other and aligned parallel to each other on the respective curved contact surface, wherein each of the surface lines of the respective curved contact surface extends in a straight line aligned tangential to imaginary circles and the axis of rotation of the clutch release bearing intersects each of the imaginary circles in a center thereof at a right angle, wherein several of the contact surfaces are arranged about the axis of rotation, and the contact surfaces follow one another spaced apart from each other, and a radially extending axial projection that projects axially beyond the contact surfaces is constructed between at least two of the contact surfaces following each other.
